Audiovox SiriusXM FMDA25 Direct Adapter

Q: does this product eliminatate having to change FM freq. everytime I drive into a different area and will this work on onyx radio

If your radio base has a FM plug in the back it will work. I think if the radio puts out at 98.1 and your radio is tuned to it, you should never have to change it.

Q: Where does the 3.5mm plug go onto the radio dock? Into the FM out or Audio out?

It goes into the Fm out. Thus will not replace the xm antenna either. You will still need to use the antenna provided. This device will only make he xm come over the radio. The audio out would work if you had a aux in on your head unit.

Q: Is this a standard modulator, i.e. can I use it with my phone as well, or does it have some proprietary Sirius stuff that would prevent me from that?

I tried plugging a standard sized (being 3.5 mm) headphone plug into the back of the Sirius XM device I have, and I'm pretty sure that the fm Jack is at a slightly different size then a regular 3.5 mm headphone jack. Plus, your talking about plugging your phone directly into the RF jack of the back of a radio without anything inbetween except this device, I'm pretty positive that you can't hook this directly up to the back of your radio and your phone, and expect it to work on the hardware level. I mean, on my Sirius XM device, it has a setting that you need to go into to select a frequency that it's going to broadcast on for the radio, so, I suspect that it won't work with your phone. So, yes, I'm pretty sure it's proprietary to the Sirius XM device.

Q: Do I need a separate antenna for the sirius radio if I use this?

Like peter mentions, if you want to be able to pick up the Sirius XM satellite with this device, you'll have to use a separate antenna for the Sirius XM dongle.
